Elena Rybakina holds an overwhelming lead in the 2026 WTA year-end No. 1 race, reflected in her 85% implied probability on Polymarket. She captured the Australian Open and US Open titles, dethroning Aryna Sabalenka to reach world No. 1 in mid-September with a commanding points cushion of roughly 2,100 over the Belarusian. Recent form and a strong overall record have reinforced trader consensus around the Kazakh, despite her early China Open exit and withdrawal from Wuhan with a foot injury. Sabalenka, Mirra Andreeva, Jessica Pegula, and Coco Gauff trail significantly in both official rankings and the live race, with limited remaining events offering little realistic path to close the gap before the WTA Finals.
